what is national income

We often hear the GDP in India. The national income of India is the sum total of income everyone earns in India. GDP, GNP are also parts of this national income.

GDP is the gross domestic products while GNP is a gross national product. Further, the savings rate and investment in the economy are the determinantal factors in the national income of India.

For a nation, the value of the final goods and services,  it produces in terms of money for the residents living in the country is the national income.

So, what is national income? It is generally for that particular fiscal year or financial year. In India, this financial year means the year from April 1st to March 31st for the next year. Thus, the formula to calculate national income is,

N.I. = C + I + G + (X -M)

Here, C stands for consumption, I stands for total investment expenditure, G stands for the expenditure done by the government, and X and M stand for export and import respectively.

X and M are interchangeable depending upon whether the trades are trade surplus or trade deficit.

To determine the estimates of national income, there are three methods:

  • Product or production method
  • Income method
  • Expenditure method
